There  is  a la’w  of  e'voluUon  operating  e-verywhere,  year  after  year  and  age  after  age.  This  la'w  tenas  to 
eliminate  the  unessential  in  things.  It  takes  a<Tvay  the  tares  from  the  -wheat;  it  removes  the  brambles  and  leaves  the 
vine;  it  destroys  the  superfluous  and  leaves  the  solid— it  condenses."

middleman  is  having  a 
severer  struggle  for  exis- 
tence than  the  men  either 
side  of  him.  The  contest  is 
sharp  enough  everywhere, 
but  the  middleman  is  at  the  focus.  He  has 
served  a useful  purpose,  and  within  a certain 
area  he  is  a necessity,  but  that  area  is  being 
circumscribed  on  both  sides.  If  the  manufac- 
turers combine,  they  concentrate  their  selling 
agencies ; if  they  remain  apart,  the  competi- 
tion between  them  becomes  so  sharp  that  they 
get  into  direct  relations  with  the  consumer. 
In  either  case  the  producer  and  the  consumer 
are  pushed  up  nearer  to  each  other,  and  the 
man  who  is  between  the  two  finds  his  position 
getting  tighter  and  tighter.  With  the  decline 
in  the  rates  of  profit  there  is  a decline  in  the 
number  of  profits  that  each  transaction  can 
sustain." — Ne'w  York  Journal  of  Commerce.

The  above  shows  that  there  has  been  no  fixed 
rule  of  proportion  in  the  alloys  of  bronze  or  brass — 
each  period,  each  country  (and  one  might  almost 
say  each  manufacturer  i following  the  formula  that  in 
the  particular  case  seemed  best  adapted  to  attain  the 
results  desired,  therefore,  in  treating  of  modern  practice, 
no  more  can  be  done  than  to  suggest  approximate  rules 
of  proportion,  as  every  scientific  manufacturer  knows 
that  the  ultimate  uses  of  the  object  to  be  made  of  bronze, 
together  with  the  color  of  finish  desired,  should  govern 
the  proportions  of  the  various  metals  entering  its  com- 
position, and  to  discuss  these  details  would  be  beyond 
the  scope  of  this  booklet.  This  company  will,  how- 
ever, cheerfully  advise  with  architects  and  owners 
who  contemplate  the  use  of  special  bronze  work  and 
aid  them  in  any  manner  within  its  power.

From  the  Mines  to  You 


take  the  crude  metals  as  they  come  from  the  mines, 
alloy  them  in  our  own  works,  cast  into  decorati’ve 
shapes,  or  roll  them  into  plates  and  draw  into  rods, 
tubes  or  mouldings,  all  in  our  own  mills;  then 
turn  into  finished  products  ready  for  use.  We 
employ  in  every  department  the  most  skillful  men  that  a liberal 
wage  scale  will  obtain  and  turn  out  the  best  these  men  can  produce,  but  artistic 
ability  is  no  excuse  for  laziness  in  our  factories.  By  watching  expenses  and  keep- 
ing our  plant  equipped  with  the  latest  improvements  in  labor-saving  machinery, 
at  same  time  reaching  direct  **  from  the  mines  to  you,"  we  are  enabled  to  supply  as 
fine  bronze  work  as  is  executed  in  this  country  at  more  favorable  prices  than 
most  other  concerns.

RULE  : To  find  thp  weight  of  bronze  or  brass  plates  compute  square  inches,  multiplying  length  by 
widtli.  then  divide  the  product  by  tlie  number  of  square  inches  contained  in  one  pound  of  the  thickness 
spec  i lied. 

EXAMPLE  : A sliect  i-i6  in.  thick  (Xo.  14  gauge)  47’-  in.  long  by  10  in.  wide  contains  475  square 
inches.  We  hnd  by  the  table  above  that  Xo.  14  gauge  bronze  sheet  requires  50  square  inches  to  the 
pound,  therefore  we  divide  475  by  50,  which  gives  us  the  weight,  9?’  lbs.  Tlic  entire  operation  being  as 
follows:  47'.'  in.  .\  10  in.  475  [ 50  • 5,

BELIEVE  in  competition  because  it  is  an  awakener  of  energies  and  promoter  of 
labor-saving  methods.  We  believe  in  the  power  of  price:  whether  the  purchaser 
seeks  a work  of  art  or  an  every-day  necessity,  he  has  the  same  wish  to  obtain 
**  his  money's  worth."  The  man  or  the  corporation  that  devises  the  means  of  pro- 
ducing any  article  of  utility  for  less  cost  than  before,  is  to  that  extent  a contributor 
to  the  public  good.  Competition  strengthens  the  desire  for  processes  that  economize,  and  is  as  desirable 
in  work  essentially  artistic  as  any  other  kind,  it  devolving  on  the  manufacturer  to  employ  men  of 
proper  ability  and  organize  them  so  that  the  efforts  of  each  man  may,  as  far  as  possible,  be  along  the 
line  of  his  special  qualifications.

inches  by  the  decimal  of  shrinkage,  thus : 6o  inches  x .0125=. 7^00 
inch,  which  shows  that  the  shrinkage  on  tliat  length  01  brass 
casting  will  be  .75,  or  ^ of  an  inch,  therefore  the  pattern  must 
be  made  full  6o3?  inches  long  in  order  to  obtain  castings  of 
desired  length.  Provide  for  shrinkage  in  width  and  thickness 
in  same  manner  as  above.

We  are  not  Ironworkers 

WHY  WE  EXCLUDE  FROM  OUR  WORKS  ALL  METALS. 

EXCEPT  BRONZE  AND  BRASS 

is  illogical  to  handle  bronze,  or  brass  and  iron  in  the  same  factory,  because 
they  are  worked  by  opposite  processes.  Bronze  and  brass  are  malleable  only 
<zuhen  cold,  iron  when  hot.  Iron  and  steel  we  harden  by  sudden  change  of 
temperature  from  hot  to  cold,  bronze  and  brass  are  softened  by  the  same 
process.  The  grinding  stones,  emery  wheels,  knives,  and  saws  that  will  cut 
one  metal  economically  are  spoiled  if  used  on  the  other.  You  cannot  use  even  common  files 
made  for  brass  on  iron,  or  if  made  for  iron  on  brass,  without  spoiling  them.  The  opposite 
character  of  the  metals,  and  necessarily  opposite  treatment,  make  it  impossible  for  any  shop  to 
skilfully  and  economically  work  in  both  kinds  of  metals. 

In  concentration  is  strength : We  have  our  entire  plant  equipped  for  the  economical  production  of  fine 
bronze  and  brass  work.  Our  trade  now  extends  to  nearly  all  commercial  centers  of  North  and  South  America  and 
parts  of  Europe.  When  you  want  something  in  this  line  write  or  phone  us  about  it. 


Sectional  full-size  drawings  of  anything  illustrated  in  this  booklet  will  be'sent  on  application  to  architects  who  may  be  interested.

IMPERISHABLE  BRONZE 


“ Among  the  many  stages  in  the  development  of  primeval  man,  none  can  have  been  of  greater  moment  in  his  struggle  for  existence  than  the 
discovery  of  the  metals  and  the  means  of  working  them.  The  names  generally  given  to  the  three  prehistoric  periods  of  man’s  life  on  earth — the 
Stone,  the  Bronze  and  the  Iron  age — imply  the  vast  importance  of  the  progressive  steps  from  the  flint  knife  to  the  bronze  celt,  and  lastly  to  the  keen- 
edged  elastic  iron  weapon  or  tool.  The  length  of  time  during  which  each  of  these  ages  lasted  must,  of  course,  have  been  different  in  every  country 
and  race  of  the  world.  The  Digger  Indians  of  Southern  California  have  even  now  not  progressed  beyond  the  Stone  Age ; while  some  of  the  tribes  of 
Central  Africa  are  acquainted  with  the  use  of  copper  and  bronze,  though  they  are  unable  to  smelt  or  work  iron,” — Encyclopedia  Britannica. 


CELEBRATED  artist  once  said : **  Heretofore  I ha’ve  painted  my  pictures  in  oil  to  crumble,  hereafter  I shall 
make  them  in  bronze  and  last  forever.** 

Because  of  its  durability,  there  is  a romance  and  sentiment  about  bronze  that  appeals  to  the 
imagination  more  strongly  than  other  materials,  for  whatever  is  made  from  bronze  approaches  nearer 
to  immortality  than  any  other  production  of  man.  Gold  and  silver  are  for  most  artistic  purposes  com- 
mercially impossible  by  reason  of  great  cost,  besides  their  intrinsic  value  expose  any  object  made  from 
them  to  the  constant  peril  of  vandalism.  Iron  or  steel  work,  however  beautifully  wrought,  will  be  lost  by  oxidization 
in  one  generation  of  exposure  to  the  elements.  The  pigments  fade  and  crumble  from  the  canvases  of  our  greatest 
paintings.  Sculptured  marble  gradually  disintegrates  and  goes  back  to  dust — even  the  ancient  languages  are  dead — 
yet  we  have  preserved  to  us  in  perfection  as  of  yesterday  old  bronze  weapons  and  utensils  made  by  our  ancestors 
thousands  of  years  before  Helen  looked  out  over  the  battlements  of  Troy,  and  before  the  first  Pharaoh  inhabited  the 
valley  of  the  Nile.  The  development  and  decline  of  art  in  all  ages  has  been  marked  by  a corresponding  fluctua- 
tion in  the  use  of  bronze,  and  the  present  revival  of  popular  taste  is  no  exception  to  that  rule,  as  is  shown  by  the  fact 
that  the  leading  architects  and  decorators  at  present  are  fast  extending  the  use  of  this  metal  as  an  architectural 
enrichment,  and  manufacturers  are  now  bringing  the  cost  commercially  within  reach,  so  that  every  architect  may  com- 
mit to  this  imperishable  material  the  best  fruits  of  his  genius.

RONZE,  as  an  architectural  enrichment,  gives  results  hardly  obtainable  at  same  cost  in  any  other 
material.  What  is  more  distinctive ; what  could  add  more  dignity  and  character  to  a building  than  a 
pair  of  massive  bronze  entrance  doors  ? What  architect  would  not  gladly  welcome  the  opportunity  of 
specifying  nothing  but  solid  bronze  for  all  visible  metal  work  ? By  using  improved  means  of  manufac- 
ture, all  the  exposed  door  and  window  trim,  sash,  mullions,  soffits,  subcornices,  etc.,  for  a building,  may 
be  made  of  indestructible  bronze  for  less  than  is  often  expended  on  perishable  materials,  and  ornament 
which  have  less  utility  or  architectural  meaning. 

We  always  esteem  it  a favor  to  have  the  privilege  of  answering  any  questions  arising  in  the  minds  of  architects  or 
owners  who  contemplate  the  use  of  bronze  work,  and  when  requested,  gladly  furnish  sucfr  details  of  construction  or  other 
information  as,  in  our  experience,  may  seem  most  applicable  to  the  case. 


STRENGTH  AND  HARDNESS  OF  COLD-ROLLED  BRONZE  COMPARED  WITH  THAT  OF  CAST  BRONZE 
Cold-rolled  and  drawn  bronze  is  harder  and  stronger  than  cast  bronze  of  like  alloy,  in  about  the  proportion  of  28  to  12.  In  other  words,  it  has  a 
resisting  power  of  about  2>^  times  that  of  cast  bronze  of  same  weight  and  thickness.

bN  a decorative  sense  bronze  and  brass  form  the  one, 
and,  perhaps,  the  only  class  of  materials  that  com- 
bine the  qualities  of  entire  permanence  with  rich- 
ness  of  effect.  They  may  be  used  tastefully  to 
some  extent  in  every  room  of  every  house  that 
is  built.  If  the  designer  will  have  recourse  to  the  great  variety  of 
colors  and  finishes  obtainable  in  these  metals,  he  need  be  limited  in 
extent  of  use  only  by  the  expensiveness  of  the  structure  under  his 
consideration.

The  Art  of  Tempering  Bronze 

HE  claim  that  the  Eg:yptians  tempered 
copper  and  bronze  to  carry  a razor  edg;e 
is  not  borne  out  by  investig:ation.  There 
is  no  piece  of  metal  tempered  by  the 
ancients  that  cannot  be  more  than 
duplicated  to-day.  An  examination  of  hundreds  of 
specimens,  alleged  to  have  been  tempered  to  the  degree 
that  steel  is  tempered,  fails  to  show  any,  and  we  know 
of  no  one  who  has  seen  such  a work.  Thus  is  the  fable 
which  has  been  believed  for  centuries,  dissipated  in  the 
light  of  modern  research. 

This  is  not  the  only  story  believed  for  centuries, 
tending  to  belittle  the  man  of  to-day,  to  make  him  the 
inferior  of  his  forefathers,  which  fails  under  the  search- 
light of  inquiry  and  science.  The  ancients  were  chil- 
dren in  mechanical  knowledge  as  compared  to  the  people 
of  to-day,  and  if  there  were  a demand  for  any  particular 
building  or  piece  of  work  such  as  was  produced  by  the 
ancients,  it  could  be  duplicated  and  improved  on  by  the 
skilled  artisans  of  the  nineteenth  century. — Ex.

Knowledge  in  Labor 

SKILLED  workman  should  always  be  thoroug^hly  familiar  with  the  raw  material  he  is  working;  or  manipulating;. 
He  should  know  whether  it  is  good  or  whether  it  is  poor,  also  whether  it  is  perfectly  adapted  to  the  particular  article 
he  may  be  producing,  and  how  it  should  be  handled  to  produce  the  best  results.  Inferior  materials  in  the  hands  of 
a workman,  who  possesses  the  proper  calculation  in,  or  knowledge  of,  all  the  details  of  his  particular  branch  of 
work,  will  produce  better  or  more  satisfactory  results  than  the  very  best  materials  in  the  hands  of  one  not  possessing 
such  knowledge.  He  should  have  sufficient  knowledge  covering  the  characteristics  of  the  material  he  is  handling 
and  the  proper  method  of  working  it,  so  that  whenever  anything  goes  wrong  he  can  detect  it  instantly  and  be  in  a position  to  locate 
the  trouble  and  apply  the  remedy.  -TTie  Journal  of  Building. 

The  soundness  of  this  argument  appeals  to  every  one,  and  it  is  the  basis  of  our  strength  as  workers  in  bronze — the  most  com- 
plex of  materials.  We  work  no  iron  ; we  work  nothing  but  bronze  and  brass.  Our  workmen  make  these  metals  a life  study.  We 
alloy  and  prepare  the  metals  in  our  own  works,  and  therefore  are  familiar  with  their  every  peculiarity,  and  know  how  to  put  into 
each  job  just  the  kind  of  metals  and  treatment  that  will  produce  the  best  results  at  a minimum  of  cost.

ABOUT  PLAIN  RAILINGS 


“BOULEVARD  ” 


This  company  has  been  35  years  in  the  manufacture  of  Bronze  and  Brass  Tubing  for  the  trade, 
and  during  the  time  has  observed  that  many  small  manufacturers  of  plain  bronze  railings,  who  obtained  their 
materials  from  us,  were,  by  lack  of  facilities  and  capital,  compelled  to  manufacture  at  so  high  an  expense 
that  we  could  do  this  for  them  at  a price  less  than  their  cost,  and  still  have  a profit  left  to  ourselves. 
This  has  led  to  the  gradual  development  in  our  works  of  a department  for  the  finishing  of  plain  railings, 
which  in  extent  and  completeness  exceeds  anything  of  its  kind  in  America.

AS  TO  THE  BENDING  OF  TUBES  • - 

Usually  a bronze  or  brass  tube  can  be  bent  to  any  radius  larger  than  three  times  its  own  diameter.  Angles  and  corners  • Q 'i  cr. 

smaller  than  this  should  be  made  of  castings  from  special  models.

Why  are  our  common  things  — the 
things  with  which  we  live,  with  which 
we  pass  our  lives — which  are  of  infin- 
itely greater  importance  to  our  education 
than  even  the  masterpieces  which  we 
see  occasionally  for  a few  hours  or  min- 
utes in  our  great  picture  galleries — why 
are  these  things  so  inferior  and  so  inar- 
tistic? — Hon.  Joseph  Chamberlain. 


If  one  of  the  busiest  men  in  the  world 
thinks  the  aesthetic  situation  grave 
enough  to  distract  him  for  a few  mo- 
ments from  his  official  duties,  it  is  time 
for  people  of  more  leisure  to  see  if  his 
plaint  is  not  well-founded.  There  is 
much  hideous  furniture  within  more  or 
less  hideous  houses,  and  there  are  hideous 
statues  without.  ■ — N.  Y.  Press. 


V 


Ruskin,  in  his  ^'Political  Economy  of 
Art,"  advances  the  argument  that  ar- 
tistic objects  are  a part  of  the  national 
wealth,  and  that  the  government  should 
protect  those  in  existence  from  destruc-  ^ 

tion  and  should  promote  their  increase; 
instructing  and  directing  its  manufac- 
turers along  artistic  lines,  by  the  estab- 
lishment in  each  community  of  some  sort  of  art  censorship.  Articles  of  artistic  design  cost  no  more  to  make  than  if  ugly.  This  applies  with 
special  force  to  such  as  are  illustrated  on  this  page.  Fireplace  brasses  are  objects  of  both  utility  and  art.  They  last  generations,  and  if  artistic  are 
handed  down  as  heirlooms,  increasing  in  value  with  every  passing  decade.
